印花彩涂板形成方法_天物彩板

印花彩色涂层板的锌层冷却后,在其表面形成一种晶粒形状,称为锌花。锌花的形成可分为多种途径。今天,我们主要带您了解以下几点:

喷水法:当镀锌板表面的纯锌溶液不凝固时,喷水(水和蒸汽、水和空气的混合物)形成晶核。未溶解的锌液从这一点向外扩散,形成锌花
表面吹风法:当印制彩色涂层板上的纯锌层即将凝固时,如果锌晶体能够通过蒸汽流或二氧化硫流顺利生长,则可以获得更大的图案。该方法还可形成致密的氧化膜,提高镀锌层的耐蚀性。
法:此方法仅适用于薄镀锌印刷层。为了达到这一目的,采用磁辊使钢丝网与锌层表面接触。当丝网接头的接触首先冷却时,产品的固体颗粒形成并成核,而其他未溶解的锌液开始结晶成核并向外膨胀形成锌火花。
锌花的生产关系到成品的质量。如果我们需要在印刷的彩色版上制作大型锌邮票,我们需要考虑多种因素的组合。以上资料仅供参考。如果您对产品有更多的细节,请随时与我们联系。

After the zinc layer of the printed color coated sheet is cooled, a grain shape is formed on its surface, which is called zinc flower. The formation of zinc flower can be divided into many ways. Today, we mainly take you to know the following points:

Water spraying method: When pure zinc solution on the surface of galvanized sheet does not solidify, water spraying (mixture of water and steam, water and air) forms crystal nucleus. The undissolved zinc liquid diffuses outward from this point to form zinc flower.
Surface blowing method: When the pure zinc layer on the printed color coating board is about to solidify, if the zinc crystal can grow smoothly through steam flow or sulfur dioxide flow, a larger pattern can be obtained. The method can also form a dense oxide film and improve the corrosion resistance of the galvanized layer.
Screen method: This method is only suitable for thin galvanized printing layer. The magnetic roller is used to make the wire mesh contact with the surface of zinc layer to achieve this purpose. When the contact of wire mesh joints is cooled first, the solid particles of the product form and nucleate, while other undissolved zinc liquids begin to crystallize and nucleate and expand outward to form zinc sparks.
The production of zinc flower is related to the quality of finished products. If we need to make large zinc stamps on the printed color plate, we need to consider a combination of factors. The above information is for reference only. If you have more details about the product, please feel free to contact us.
